Abstract
A guide assembly for a downhole tool and related method is disclosed. The guide assembly comprises a guide housing, flappers, and a driver. The guide housing has a passage to receive the downhole tool therethrough. The flappers are movably positionable about the passage to selectively reduce an inlet thereto. The driver comprises a translator rotationally coupled to the flappers via the rods and an actuator to rotate the translator. The flappers are rotatable between the closed and the open position by the driver whereby passage of the downhole tool into the passage is selectively permitted. The translator may be a cam, gear, or rotary driver. The actuator may axially or rotationally drive the translator.
